A new section of a freeway is to be designed with a free-flow-speed of 65 mph along of 0.75 mile on 5% upgrade. The expected traffic volume is 4200 v/hr. The traffic composition is 15% trucks, 5% recreational vehicles, and 10 % buses. The peak hourly factor is 0.9, the unfamiliar driver factor is 0.95. If the design requirement is to target a level of service (B), how many lanes must be provided to satisfy the design requirement?

- You are designing a freeway as a passenger-car only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS C using the 40th highest annual hourly volume (K = 0.116).

It is estimated that the freeway will have a free flow speed of 70mi/h. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume. Use k =0.11.a six-lane multilane highway (three lanes in each direction) has a peak hour factor of 0.90, 11-ft lanes with a 4-ft right-side shoulder, and a two-way left turn lane in the median. the directional peak hour traffic flow is 4000 vehicles with 10% large trucks and buses and 2% recreational vehicles. the driver population factor has been estimated at 0.95. what will the los on this highway be on a 4% upgrade that is 1.5 miles long if the speed limit is 55 mph and there are 15 access points per mile
- A four-lane basic freeway segment on level terrain is being redesigned. The current roadway has 12 ft lanes with 4 ft shoulders. The proposed alignment would expand to six 11-ft lanes with 2 ft shoulders. The road carries 3000 vehicles in the peak hour in one direction, with 925 coming in the peak 15 minutes. The truck mix is 70/30 and makes up 10% of traffic. What is the density and LOS (level of service) before and after the proposed change?Isabel A six-lane freeway (three lanes in each direction) in a scenic area has a measured free-flow speed of 55 mi/h. The peak hour factor is 0.80, and there are 8% large trucks and buses and 6% recreational vehicles in the traffic stream. One upgrade is 5% and 0.5 mi long. An analyst has determined that the freeway is operating at capacity on this upgrade during the peak hour. If the peak-hour traffic volume is 3900 vehicles, a.) Determine fy (Express in three decimals)A 6-lane new urban freeway is suggested to be designed with the following data: F.ADT = 45000 vpd, design hour factor= 0.12 and directional split = 65%.

- It is estimated that after 25 years in a section of highway, the average daily traffic will be 15000 vehicles. It is found that ratio of design hourly volume to the average daily traffic was 15%. The one way traffic volume in the predominant direction is 60% of the two way design hourly volume. Determine the directional ?design hourly volume after 25 years **Eight lane urban freeway is on mountainous terrain with lane width of 12 ft, right shoulder lateral clearance of 4 ft, and 12 ramps over the 6-mi analysis segment. The traffic stream consists of familiar road users. Peak hour volume for a directional weekday of 5200 vehicles is observed with 500 vehicles arriving in the most congested 15-min period. If the traffic stream has 10% large trucks and 12% buses and 10% recreational vehicles, determine the heavy vehicle adjustment factor. Round your answer to 3 decimal places. Exclude the unit in the answer box.A six-lane freeway (three lanes in each direction) in a scenic area has a measured free-flow speed of 55 mi/h. The peak hour factor is 0.80, and there are 8% large trucks and buses and 6% recreational vehicles in the traffic stream. One upgrade is 5% and 0.5 mi long.
